in thread TDD with Coverage Analysis. Wow.

Can you invoke it directly in the test script as &{$SIG{__DIE__}} and test accordingly from there?

Only if the !$^S branch doesn't die (and doesn't call something that does). I should have made that clearer in my original post. Will fix. Thanks.

# potential workaround
use constant DEFAULT_FILENAME => 'foo.txt';
my $filename = prompt_for_filename() || DEFAULT_FILENAME;

I don't see how the second alternative of the || could ever be false (i.e. the coverage would never be 100%).

Update: Ah, I see.

    It can't, but just like with xdg's note about my $value = $some_other_value || undef;, Devel::Cover is also smart enough to realize that DEFAULT_FILENAME is a constant and removes the truth table entries of it being false, so that you can get to 100% coverage for that line.
